Example 1: Sum of All Values in NumPy ArrayThe following code demonstrates how to calculate the sum of all elements in a NumPy array.For this task, we can apply the sum function of the NumPy library as shown below:print(np.sum(my_array)) # Get sum of all array values # 21...
numpy.sum(a, axis=None, dtype=None, out=None, keepdims= Parameters: a :array_like Elements to sum. axis :None or int or tuple of ints, optional Axis or axes along which a sum is performed. The default, axis=None, will sum all of the elements of the input array. If axis is neg...
Axis or axes along which a sum is performed. The default, axis=None, will sum all of the elements of the input array. If axis is negative it counts from the last to the first axis. If axis is a tuple of ints, a sum is performed on all of the axes specified in the tuple instea...
The sum() function is used to calculate the sum of array elements along a specified axis or across all axes. The sum() function is used to calculate the sum of array elements along a specified axis or across all axes. Example import numpy as np array1 =
If we pass only the array in the sum() function, it’s flattened and the sum of all the elements is returned. import numpy as np array1 = np.array( [[1, 2], [3, 4], [5, 6]]) total = np.sum(array1) print(f'Sum of all the elements is {total}') ...
numpy.sum(a,axis=None,dtype=None,out=None,keepdims=False)[source] Sum of array elements over a given axis. Parameters: a: array_like Elements to sum. axis: None or int or tuple of ints, optional Axis or axes along which a sum is performed. The default (axis=None) is perform a su...

Sum the elements of a 1-d array with np.sum Let’s start with the simplest possible example. We’re going to create asimple 1-dimensional NumPy array using the np.array function. np_array_1d = np.array([0,2,4,6,8,10])
numpy.sum(a,axis=None,dtype=None,out=None,keepdims=<no value>,initial=<no value>) 文档中对sum函数只用了一句话描述:Sum of array elements over a give axis(对指定坐标轴axis上的元素进行求和)。它的返回结果: An array with the same shape as input, with the specified axis removed(返回结果的sh...
